In fact, carelessness is a big problem. Needless to say here, the microscopic world of molecules, atoms and electrons in physical chemistry is a little careless, and it is a thousand miles away; Needless to say, aerospace engineering, lunar exploration engineering, these sophisticated problems, we all know that the American Apollo spacecraft crashed because of a small heat insulation tile. Let's not talk about this. Let's start with the story of "Fat Sister-in-law going back to her mother's house".
Fat sister-in-law is impatient and thick-skinned One night, she received a letter from home. After reading the first sentence, she was anxious: "Father is seriously ill ..." Before dinner, she picked up the child from the bed and hurried home. There are no buses in the country at night, so we have to walk. Passing through a field of wax gourd, she fell down and threw the child off her back. She quickly got up, picked up the child and left. It was nearly midnight when I arrived at my father's house. Father's family got up quickly, only to find his father holding a cup of tea for himself. It turned out that she had not finished reading the contents of the letter from home. "My father is seriously ill and has recovered." Only then did she remember to put the child down from her back, but when she put it down, it was a big melon. This gave her a big fright: she fell into the melon field and carried it like a child. She hurried back to Gua Tian to find the children. I searched for a long time in Gua Tian, and only found a pillow. Now she panicked and ran home. When I got home, the child was still crying in bed. It turned out that when she went out, she was carrying a pillow and left in a hurry.
Fat sister-in-law made some careless mistakes in life, which just made us feel ridiculous. However, some things are not just ridiculous questions.
A famous company recruited employees, 10 Gao Feisheng, and passed the final exam. This exam will finally decide their fate. The test papers have been distributed. As you can see, the topic is simple, but there are many problems, which need to be completed within 3 minutes. They quickly picked up their pens and began to do it. As a result, only one person finished the paper in three minutes, and he was admitted. The other nine students were outraged, and the question was too bad. It takes two minutes to finish so many questions. How can they finish it in three minutes? The examiner smiled and said, after reading the last question, you will understand. Looking at it, I really have nothing to say. The original title is this:
Question 1: Please read all the questions.
Question 2: Please write down your name and age.
……
Last question: You only need to do the second question.
If you are one of the candidates, how do you feel?
I remember that when students answer questions, the teacher often asks us to examine the questions first. This is a very important procedure. You must read the topic and then understand the requirements of the topic. Find out the problem and start solving it. Otherwise, it is likely to be the result of doing the opposite and answering irrelevant questions.
By extension, no matter what we do, we need a good style of work. Don't jump to conclusions, find out the ins and outs of things, find out the truth of things, and then deal with them. In short, we must first do a good job in investigation and research.
It is often said that there is no right to speak without investigation. In this respect, an ancient man did a very good job. He is Qi Weiwang, the king of Qi in Zou Ji's satirical Book of History, and everyone is familiar with him. When he heard about himself, he often praised Acheng's doctor, saying that he was the best among local officials, and vilified Dr. Jimo every day, saying that he was the worst. After listening to these reports, Qi Weiwang didn't believe them. But to send effective personnel to investigate on the spot. As a result, Jimo is well managed, the land is fully developed, the people are well fed, the government is fair and just, and there is no business backlog. Qi Weiwang understood that Dr. Jimo was vilified because he couldn't flatter the people around me, so no one praised him or put in a good word for him in front of me. Therefore, after observation, Qi Weiwang summoned Dr. Jimo and made him heavy.
On the contrary, Qi Weiwang sent a field trip, Acheng was badly managed, the fields were barren and the people were poor. Once upon a time, Zhao captured a city. As a doctor, he didn't go to the rescue. Wei captured one, but as a doctor, he didn't know. Qi Weiwang knew that Dr. Acheng enjoyed a high reputation because he bribed his left and right sides with a large sum of money, so that people kept saying good things about him in front of him. Qi Weiwang is very decisive. He also summoned Dr. Acheng and killed him that day, and also killed all the people around him who praised Dr. Acheng.
Modern society is an information society, and it is more necessary to investigate and fully grasp information resources. If we don't know the information, we can't move. There was a graduate student who devoted all his financial and material resources to a new invention after graduation. Many things happen. A year later, he really invented this technology. When he applied for related patents with confidence, he was told that his technology had been invented as early as ten years ago. Therefore, his invention is just one of the meaningless repetitive work of human beings. He wasted a year, not counting, and made his relatives "losers"-owed a lot of debts.
For ourselves, the most important thing to emphasize the fine style is to make ourselves a "conscientious person" in our study and life. Let's talk about this problem by taking solving problems as an example.
If we are faced with a math application problem, what are our usual steps to solve it? I wonder if there should be such steps: the first attempt, the second thought, the third choice and the fourth solution. In fact, solving various problems in our study, work and life is a "problem-solving" process, which can generally be handled well.
"Examination" means examining questions. When things happen, the first thing to look at is the nature of the problem. What are the known conditions? What matters need to be dealt with? What are the requirements? We must understand all this.
"Thinking" means thinking about ways to solve problems. According to the knowledge learned at ordinary times, consider all possible methods, such as what formulas and theorems to use, what principles to adhere to, how to deduce calculations, and so on.
"Select" is the first choice. For those possible solutions, we should compare which one is faster, better and more economical. This is actually a decision-making process. To learn to choose is nothing more than four words: weigh the pros and cons. Take the lesser of the two evils, and take the advantage of the two benefits, so as to maximize efficiency and benefit.
"Solution" is a concrete realization. No matter how good the method is, it is empty talk if it is not implemented. To solve the problem, the calculation is deduced step by step according to the relevant requirements. Generally speaking, as long as the method, formula and theorem are correct, the problem can be solved satisfactorily.
